Java Example - Using Enumeration to Traverse HashTable
Java ExampleThe following example demonstrates how to use the hasMoreElements and nextElement methods of the Enumeration class to traverse and output the contents of a HashTable:
Main.java file
import java.util.Enumeration;
import java.util.Hashtable;
public class Main {
public static void main(String[] args) {
Hashtable ht = new Hashtable();
ht.put("1", "One");
ht.put("2", "Two");
ht.put("3", "Three");
Enumeration e = ht.elements();
while(e.hasMoreElements()){
System.out.println(e.nextElement());
}
}
}
The output of running the above code is:
